Which of the following groups best illustrates a sample?
选项:
A.The set of all estimates for Exxon Mobil’s FY2015 EPS
B.The FTSE Eurotop 100 as a representation of the European stock market
C.UK shares traded on 13 August 2015 that also closed above £120/share on the London Stock Exchange

The FTSE Eurotop 100 represents a sample of all European stocks. It is a subset of the population of all European stocks.
不是说是 a set of xxx么,那就应该是这些数据里的一组数据,不就是sample了?
